  • This ferry is associated with a motor control which allows it to move transversely to place the correct pallet on the conveyor.
  • the latter is itself provided with means of training the palette which can for example consist of a self-propelled trolley comprising means for hanging it to the selected palette and means for its guiding and steering in translation along the track main, in order to place the pallet at different positions associated with the different workstations of the small island.
  • a self-propelled trolley comprising means for hanging it to the selected palette and means for its guiding and steering in translation along the track main, in order to place the pallet at different positions associated with the different workstations of the small island.
  • the invention therefore also relates to a device for pallet change for a pallet conveyor.
  • the first object of the invention is therefore a device crossing of pallet conveyors, comprising a central part and portions of conveyors connected to the central part, each of these conveyor portions including a traffic lane to support pallets and means for driving these pallets along this traffic lane.
  • the lanes of at least two of the portions of conveyors are arranged at different altitudes
  • the central part has lifting means to move vertically a pallet located on this central part between altitudes corresponding to different altitudes traffic lanes for conveyor portions
  • this pallet has peripheral hooking means arranged opposite at least one of the portions of conveyors, can be engaged and disengaged during a vertical displacement of this pallet caused by aforementioned lifting means with hooking means counterparts associated with this portion of conveyor.
  • homologous attachment means can be combined directly or indirectly to the conveyor portion corresponding. More specifically, these fastening members counterparts can be carried either by a pallet located on the portion of the conveyor to which they are associates, either directly by the training means of this portion of conveyor being integral with a carriage sliding parallel to the traffic lane of this portion of conveyor.
  • the attachment means are hooks of the shape cooperation type.
  • the device has two main conveyor portions, the traffic lanes extend at the same altitude in a main direction on either side of the central part and at least a portion of conveyor secondary whose lane extends to a different altitude in a substantially secondary direction perpendicular to the main direction.
  • the traffic lanes portions of main conveyors are located one altitude lower than that of the taxiway of the portion of secondary conveyor.
  • the device comprises two portions of secondary conveyors including the traffic extend at the same altitude depending on the secondary direction on either side of the game central.
  • the central part includes a central portion of main conveyor having a fixed traffic connecting the traffic lanes of the two portions of main conveyors, so that these three portions form a continuous portion of conveyor main, and a central portion of secondary conveyor having a traveling lane vertically between a high position in which it extends into the extension of the taxiway for the portion of secondary conveyor and a low position in which it authorizes the circulation of a pallet on the way to circulation of the central portion of main conveyor.
  • the portions of conveyors main form a main conveyor, this conveyor having training means which include a carriage mounted to slide on a slide parallel to the main conveyor lane equipped with retractable means for coupling to a pallet carried by the main conveyor traffic lane.
  • the invention also relates to a device pallet change for pallet conveyor, comprising a crossing device according to the invention, in which the secondary conveyor portions form parking lanes for pallets.
  • the peripheral attachment means of this palette which are associated with the portion of main conveyor on which the pallet is placed replace are engaged with the hanging means corresponding devices in this palette to be replaced.
  • the means of driving the conveyor portions main then move the two pallets thus coupled, so that the pallet to be replaced is placed on the central part, while the replacement palette is placed on another portion of conveyor main adjacent to the central part.
  • the means of lifting, and therefore the pallet to be replaced, are placed at the altitude corresponding to the portion of secondary conveyor on which we want to park this palette.
  • the peripheral attachment means of this pallet are disengaged from the peripheral attachment means replacement pallet.
  • the means for driving the portion of secondary conveyor drive the pallet to be replaced on this portion up to a parking position in which is fully clear of the central part. We thus realized the pallet change desired.

  • the initial step is illustrated in Figure 1.
  • Pallets 15 and 17 are both arranged on the main conveyor 5 and are coupled to each other by their hooks 21, the central part 13 being in position low.
  • Pallet 19 is placed on portion 7 of the secondary conveyor 11 in standby position.
  • the central part 13 is actuated to come into its high position and place the pallet 17 at the altitude of track 27 of the secondary conveyor 11.
